Abstract

The effect of various metal complex catalysts of tetraaza-(14)-anurene on the thermal decomposition of ammonium nitrate, ammonium perchlorate and a solid propellant containing ammonium perchlorate as an oxidizer was studied by thermal analysis and burning rate measurements. The following results were obtained.
  A metal complex, which had iron or vanadium as a central metallic ion, showed high activity during the thermal decomposition of ammonium nitrate. Especially, this activity became high when chloride and perchlorate ions were combined with iron or vanadium ions.
Iron and vanadium catalysts also had high activity during the thermal decomposition of ammonium perchlorate and its solid propellant. For the solid propellants which contained iron or vanadium complexes as catalysts, the burning rate increased by 1.6 times and their n index decreased to 80% compared to the burning experiments without a catalyst at a pressure of 5.0 MPa.
